gpg Signature

[Rasoul Hajikhani]

Hello there,
I have a question about gpg signature that I am hoping some one may be
able to answer. I have created a signature file with the '--sign'
option. The file contained plain text and now I would like to de-sign
the file, that is I want to convert the content of the file to plain
text again.
The gpg man pages does not mention how it is done. It talks about
'verifying' a signature, but I would like to get my plain text back. Is
that possible?

Thanks In Advance
